4. Prepared by Jennifer Kreie, New Mexico State UniversityHosted by the University of Arkansas Microsoft Enterprise Consortium Sort output from the Student-Team database List students and their team ID. Sort by team ID. /* List students and their team ID. Sort by team ID. */ select std_teamID, stdmajor, stdfname, stdlname from students order by std_teamID ; 4

5. Prepared by Jennifer Kreie, New Mexico State UniversityHosted by the University of Arkansas Microsoft Enterprise Consortium Sort by more than one column. List students by team and major. /* List students and their team ID. Sort by team ID and major. */ select std_teamID, stdmajor, stdfname, stdlname from students order by std_teamID, stdmajor ; /* Another way to identify which columns to sort by using numbers. */ select stdfname, stdlname, stdmajor, std_teamID from students order by 4, 3 ; 5

6. Prepared by Jennifer Kreie, New Mexico State UniversityHosted by the University of Arkansas Microsoft Enterprise Consortium Column aliases improve readability Columns in the output display can show standard text rather than field names. /* Use column aliases column headings in output. */ select std_teamID "Team", stdmajor "Major", stdfname "First Name", stdlname "Last Name" from students order by std_teamID, stdmajor; 6

7. Prepared by Jennifer Kreie, New Mexico State UniversityHosted by the University of Arkansas Microsoft Enterprise Consortium Combine columns into a single output column Sometimes you can improve output readability by combining columns, also known as concatenated columns. 7 /* Combine 2 columns into one (concatenate columns). */ select std_teamID "Team", stdmajor "Major", stdfname + ' ' + stdlname "Student" from students order by 1, 2; select std_teamID "Team", stdmajor "Major", stdlname + ', ' + stdfname "Student" from students order by 1, 2, 3;

8. Prepared by Jennifer Kreie, New Mexico State UniversityHosted by the University of Arkansas Microsoft Enterprise Consortium Creating a calculated column The concatenated column we just created in one example of a calculated column. You can also actually do calculations. 8 /* Add a calculated column. */ select eval_id, eval_score_id, eval_item_id, score, score *.1 "Points Earned" from eval_items_scores order by eval_id, eval_score_id, eval_item_id;
